2 Kings 2:18-21

18When they returned to Elisha, who was staying in Jericho, he said to them, “Didn’t I tell you not to go?”

Healing of the Water 19The people of the city said to Elisha, “Look, our lord, this town is well situated, as you can see, but the water is bad and the land is unproductive.”

20“Bring me a new bowl,” he said, “and put salt in it.” So they brought it to him. 21Then he went out to the spring and threw the salt into it, saying, “This is what the LORD says: ‘I have healed this water. Never again will it cause death or make the land unproductive.’ ”
